How the math works
10 ft × 10 ft = 100 sq ft. At 3 inches deep that's 100 × 3 ÷ 12 = 25 cubic feet, and ÷ 27 = 0.93 cubic yards. Adding 10% gives 27.5 cubic feet to buy.
How deep should it be?
For a top-up on an existing gravel surface, 2 to 3 inches is common. New driveways and paver bases are built thicker, in compacted layers: Unilock's guide calls for 6 to 8 inches of base under patios and walkways and 10 to 14 inches under paver driveways.
